Definitions
- the immune system is designed to target a large number of foreign antigens such as those presented by allergens and pathogens.
- Immune responses to specific antigens rely on the white bloods cells, and specifically the B cell and T cell populations. B cell responses typically result in the production of antibodies specific to the antigen while T cells are involved in cell mediated responses.
- T cells are subclassified into two broad populations. Helper T cells are identified by the surface marker CD (Cluster Designation) 4, and are mainly involved in assisting in antibody production and induction of various immune responses. Cytotoxic T cells are distinguished by the CD8 marker and play an important role in recognizing, destroying and eliminating tumor cells and virus- infected cells, but do not produce an antibody specifically reacting with an antigen. Cytotoxic T cells directly recognize and act on antigens (typically antigenic peptides) from a target cell which are associated with major histocompatibility complex (MHC) Class I molecules present on the surface of the target cell membrane.
- MHC major histocompatibility complex
- the effective number of engineered CD4+ cells is about 5 x 10 6 and the effective number of engineered CD8+ cells is about 5 x 10 6 .
- the subject is an adult human, between about 10 10 and 10 11 each of CD4+ and CD8+ cells may be used.
- the adoptive immune response is capable of preventing establishment of a new tumor or infection.
- the experiments described herein demonstrate for the first time in vivo that the provision of engineered antigen- specific CD4 + T cells can significantly improve anti-tumor responses, maintain persistence of transferred T cells and induce a potent recall response after tumor rechallenge. This is a substantial advance over the adoptive immunotherapy methods of the prior art.
- FIG 1 shows expression of the scFv-CD28- ⁇ receptor in transduced CD8 + and CD4 + primary mouse T cells.
- Splenic T cells enriched from BALB/c mice were depleted into CD4 + and CD8 + T cells subsets or left as unfractionated T cells prior to retroviral transduction with the scFv-CD28- ⁇ receptor.
- Transduced unfractionated T cells consisted of 80-85% CD8 + T cells and -10% CD4 + T cells (A) while isolated populations consisted of greater than 90% CD8 + (C and G) or QD4- T-cells (i and-l).
- FIG 3 shows increased transfer of engineered CD4 + T cells enhances tumor- free survival of mice.
- A Groups of 10 scid mice were injected i.v. with 5x10 6 MDA-MB-435-erbB2 cells at day 0 prior to i.v. injection of scFv-CD28- ⁇ transduced T cells at day 5.
- mice that received 1 :1 CD4 + (5 x 10 6 ) and CD8 + (5 x 10 6 ) scFv-CD28- ⁇ transduced T cells (A, E and I), unfractionated transduced T cells (10 7 ), mouse #1 (B, C and F), mouse #2 (G, J and K), or 1 :1 CD4 + (5 x 10 6 ) and CD8 + (5 x 10 6 ) scFv- ⁇ -CEA- ⁇ transduced T cells (D, H and L) were stained by H&E, with anti-CD4 (green), anti-CD8 (red) and anti-CD11b (blue) mAbs (E-H) or with anti-tag (red) and anti-CD11 b (green) mAbs (I-L).
- mice normal scid mice were challenged with 5 x 10 4 4T1.2-erbB2 (closed squares) or 4T1 -parental tumor cells (closed triangles) (D)
- 4T1.2-erbB2 tumor cells open squares
- long-term surviving mice were challenged subcutaneously with either 5 x 10 4 cells (open triangles) or 5 x 10 3 4T1.2-erbB2 tumor cells (open squares) and survival was statistically compared (*p ⁇ 0.001 , Mann-Whitney test).
- the molecule capable of binding to the antigen includes sequences from TCR- ⁇ and/or CD28 co-stimulatory signalling domains, or functional equivalents thereof.
- Adoptive immunotherapy strategies involving the genetic modification of autologous T cells with scFv chimeric receptors or TCR genes is gaining wider acceptance as a promising treatment for cancer. Indeed, recent advances in the design of scFv receptors comprising both primary TCR- ⁇ and CD28 co-stimulatory signaling domains have demonstrated striking results against early subcutaneous tumor growth and tumor metastases in mice after adoptive transfer (Haynes et al, 2002a; Haynes et al; 2002b).
- antigen is selected from the group consisting of Le y , EGFR, PMSA, G250, NY-ESO1 , CD20, CD19, idiotype Ig, p53, ras, CEA, MUC1 , GD2, and HuD.
- antigen is Le y or erbB2.
- the adoptive immune response leads to the complete eradication of the infection or tumor.
- the present invention provides a composition for adoptive immunotherapy including an engineered CD4+ T cell and an engineered CD8+ T cell.
- mice BALB/c and BALB/c scid/scid (scid) mice were purchased from The Walter and Eliza Hall Institute of Medical Research, Melbourne, Australia.
- BALB/c IFN-Y -deficient mice BALB/c IFN-v " ' " mice were bred at the Peter MacCallum Cancer Centre, Melbourne. Mice of 6 to 12 weeks of age were used in experiments that were performed in accordance with animal experimental ethics committee guidelines.
- each T cell subset was initially isolated by labelling with anti-CD4 or anti-GD8 ⁇ magnetic- beads (Miltenyi Biotec) and passed-through a-MACS- depletion column. The efficiency of isolating separate T cell subsets was verified by flow cytometry.
- Enriched CD8 + , CD4 + or unfractionated T cell cultures (10 7 cells) were immediately co-cultured with retrovirus-producing packaging cells (5 x 10 5 ) for 72 h in DMEM supplemented with with 4 ⁇ g/ml polybrene, 5 ⁇ g/ml PHA (Sigma, St Louis, MO) and 100 U/ml rlL-2. Following co-culture, T cells were analysed for transduction efficiency by flow cytometry.
- Mouse CD8 + , CD4 + or unfractionated T cells (10 6 ) transduced with the scFv- ⁇ -erbB2-CD28- ⁇ receptor or mock CD8 + and CD4 + T cells transduced with an empty LXSN vector were co-cultured with 10 6 erbB2 + MC-38-erbB2, MDA-MB-435-erbB2 or 4T1.2-erbB2 tumor cells or erbB2- MC- 38, MDA-MB-435 or 4T1.2 parental tumor cells in 12-well plates for 20 h. No exogenous IL-2 was added. Supernatants were harvested and IFN- ⁇ , lL-2, GM- CSF, and IL-4 production by transduced T cells was determined by ELISA.
- EXAMPLE 6 Antigen-specific response to tumor rechallenge.
- mice An important-issue with -regard to any-cancertherapy is- whether the -specific- treatment can induce a secondary response to tumor relapse.
- long term surviving mice >100 days
- transduced CD8 + and CD4 + T cells were injected with an i.v. dose of 5x10 6 MDA-MB-435-erbB2 tumor cells.
- all mice were able to totally eradicate a second dose of MDA-MB-435-erbB2 tumor (Fig. 6 A).
- Normal scid mice injected with MDA-MB-435-erbB2 cells did not survive (Fig. 6 A).
